I use Firefox with AVG and recently upgraded my AVG to to new improved 7.5. The download options were for Windows and Linux only. There is no choice for FireFox. I downloaded the one for Windows? Is it okay to use FireFox with AVG/Windows or should I have downloaded the one for Linux or does it matter? Please let me know. Also, if I shouldn't be using AVG with my FF would someone give me some advice on maybe another good free anti virus program?
